Check the send-fax resolution setting
If the product was unable to send a fax because the receiving fax machine did not answer or was busy, the
product attempts to redial based on the redial-on-busy, redial-on-no-answer, and redial-on-communication-
error options.

Check the error correction setting
Usually, the product monitors the signals on the telephone line while it is sending or receiving a fax. If the
product detects an error during the transmission and the error-correction setting is On , the product can
request that the portion of the fax be resent. The factory-set default for error correction is On .
You should turn off error correction only if you are having trouble sending or receiving a fax, and you are
willing to accept the errors in the transmission. Turning off the setting might be useful when you are trying to
send a fax overseas or receive one from overseas, or if you are using a satellite telephone connection.
1. From the Home screen on the product control panel, touch the Setup button.
2. Touch the Service menu.
